The country also has 402 kilometers (249 miles) of coastline on the Bight of Biafra, part of the Atlantic Ocean. The topography of Cameroon is varied, ranging from tropical rain forests in the south to mountainous highlands in some western central regions, and semi-arid savanna in the far north.
The Ionisphere bounces radio waves back to earth and regulates the amount of radiation that gets to the lower atmospheres. It all depends on the Sun's activity. The stratosphere is what actually protects us from the UV rays of the sun.
The ionosphere is defined as the layer of the Earth's atmosphere that is ionized by solar and cosmic radiation. Short wave radiation that penetrates the Earth's atmosphere does not reach the surface.A few examples of short wave radiation are x-rays, ultraviolet and gamma rays. When these waves pass through the atmosphere, they ionize molecules of oxygen and nitrogen and create a thin ionized region known as the ionosphere.he ionosphere is very important because it can be used to help transmit radio waves across the globe. The radio waves are able to bounce off the ionosphere for communication purposes.
